PATENT CEEIcE JOHN O. OSBORNE, OF CHICAGO, ILLINOIS.

IMPROVEMENT IN RAILWAY-CAR HEATRS.

Specification forming part of Letters Patent No. l 86,495, dated January 23, 1877; application filed March 15, 1876. i v

Toall lwhom it may concern:

Be it known that I, JOHN O. OSBORNE, of the city of Chicago, in the county of Cook and- State of Illinois, have invented a new and useful Improvement in Steam Heat Apparatus for Railway-Cars, which is fully described in the following specification, reference being had to the accompanying draw-V ings, in which- Figure l is the side elevation of a railwaytrain with my heater attached. Fig. 2 is a top or plan View of my heater detachedfrom the cars, and Fig. 3 isa perspective View' of the portion of the heater which is attached to one car.

My invention consists in the peculiar arrangement and comblnation of vsteam pipes and couplings in connection with railway-cars, and a steam-generator, as will be hereinafter fully described, whereby the cars are heated by steam generated at a distance from them, each car being warmed independently of the In the accompanying drawings, A represents a pipe, which is connected with the steam-generator. I have shown itconncted with the locomotive boiler B. There are steam pipes O arrangedl in each car suitable for heating it. These pipes are connected to separate pipes D D' D, one for each car, which extend to the steam-generator. The pipe D", that conducts steam to the rear car, extends beneath all the other cars, being coupled between the cars .by couplers E. Each car has a pipe, D Dl D", &c., 4connected to its heating-pipes at its forward end, and extending to the steam generator, and these pipes are coupled together by an ordinary coupling, E, placed in a exible tube that can be readily coupled and uncoupled as` the cars are attached to or detached from the train.

F are steamcocks for controlling the admission of steam to the heating-pipes, and G are similar cocks for shutting the steam oft' from any of the pipes leading to the cars at the generator.-

H is a cross-pipe at either end of the car, for connecting the pipe D D D, &c., to the heating-pipe, so that the heater may be connected to pipes D D D", 85e., at either endrof the car, and thus accommodate the turning of the car to run the other end foremost.

By .coupling the pipes D D D, &c., between the cars when the train is `made up, the steam-heating apparatus is ready for usg, and the cars can be heated without haviigany tire in the cars.

The steam is generated in a locomotiveboiler, or a steam-generator suitable for generating steam for all the cars, and is conveyed to each car in 'suitablelqua'ntities to heat the cars, as described.l

I avoidl the danger arising from the ire in the cars in cases otaccident. This I deem of great importance, and I accomplish it by a simple and inexpensive device, that `can be readily handled and controlled by any ordinary railway employs.

Having fully described the construction and operation of my invention, what I claim, and desire to secure by Letters Patent, is-

'1. The combination, with railway-cars, of the steam-pipes C, arranged to heat the-cars, and the pipes D D D, &c., one for each car, to convey steam from the pipe A to the pipes O, and constructed as described, so as to be coupled between the cars, substantially as specified and shown.

2. The combination of pipes O .and inde- .pendent pipes D'D Dl with the pipes H and suitable coupling devices, whereby the cars are adapted tobe attached to the steam-supply pipes at eitherend, substantially as set forth.

3. The combination of the receiving and distributing pipe A, the steam-generator, the independent pipes l) D', &c., attached thereto, the stop-cocks Gr, and the pipes E, with stop-cocks F, substantially as and for the purpose set forth.
